Product Specification

-
This o-ring is supplied in AS568-260 black Buna-N (Nitrile) 70 Shore A with an inside diameter of 6.484 in (164.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.762 in (171.75 mm), catalogued under part number H70MD260. It delivers dependable bidirectional sealing in a compact groove envelope.

The compound resists water, hydraulic fluids, and greases and lubricants. Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or ketones will shorten service life.

This item is metal detectable for HACCP and foreign-body control programs. It sees regular use in hydraulic and pneumatic systems, agricultural equipment, and fluid power.

Reference part number H70MD260 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
